Long-acting rust-preventing oil

Abstract

The invention discloses long-acting rust-preventing oil. The long-acting rust-preventing oil consists of the following raw materials in parts by weight: 0.2-0.5 part of gaseous-phase silicon dioxide, 50-70 parts of 100sn base oil, 2-4 parts of polymethyl methacrylate, 3-7 parts of dodecyl phenyl succinic acid, 1-2 parts of 1,2,3- benzotriazole, 2-4 parts of polyvinyl alcohol, 2-3 parts of alkenyl succinate, 1-2 parts of tetramethylammonium nitrate, 2-3 parts of 4-oxobutanoic acid methyl ester, 3-6 parts of ethyl acetate, 0.2-0.5 part of isophorone diisocyanate, 0.6-2 parts of ammonium tungstate and 14-20 parts of rear-earth rust-preventing hydraulic oil. The long-acting rust-preventing oil disclosed by the invention is added with the rear-earth rust-preventing hydraulic oil; an alkyl ketone dispersion fluid can be used for improving the mobility and improving the reaction activity; the added rear earth ions and OH<-> produced in an oxygen-up corrosion process can produce insoluble complex on a metal substrate surface to slow down corroded electrode reaction, so that very good controlled-release effects are achieved.

Description

[0001] technical field [0002] The invention mainly relates to the field of lubricating oil, in particular to a long-acting antirust oil. Background technique [0003] During the storage, transportation and use of metals, due to the influence of water vapor, oxygen, acid, alkali, salt and carbide in the ambient atmosphere, physical and chemical changes will occur under certain temperature, humidity and time extension conditions. rust due to change. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal corrosion is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution. Corrosion is one of the main forms of damage to fasteners, which will cause great losses to automobiles, motorcycles, various vehicles and machinery. . According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national econ...

Problems solved by technology

According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national economy. Material is the most common method, and there are many problems in today's anti-rust oil, such as corrosion resistance, durability, adhesion, poor, prone to hardening, falling off, cracking, so it is necessary to continuously improve the anti-rust oil Comprehensive quality, to achieve better rust and corrosion inhibition effect
